Warning!
Any accumulation of snow and ice should be
removed from the rear window before driv-
ing. Visibility could otherwise be impaired,
endangering you and others.
i
If the rear window defroster switches off too
soon and the indicator lamp goes out, this indi-
cates that too many electrical consumers are op-
erating simultaneously and the load on the
battery is reducing available voltage. The system
responds automatically by deactivating the rear
window defroster.
Maximum cooling MAXCOOL (USA only)
If U is selected on both the left and
right side and there is a high demand for
cooling, the display "MAXCOOL" appears
in the COMAND display.
This provides the fastest possible cooling
of the vehicle interior (when windows and
tilt/sliding sunroof are closed).
i
Maximum cooling MAXCOOL is only avail-
G
able when the engine is running.

Air recirculation mode

Switch to air recirculation mode to prevent
unpleasant odors from entering the vehicle
from the outside (e.g. before driving in a
tunnel). This setting cuts off the intake of
outside air and recirculates the air in the
passenger compartment.
Warning!
Fogged windows impair visibility, endanger-
ing you and others. If the windows begin to
fog on the inside, switching off the air
recirculation mode immediately should clear
interior window fogging. If interior window
fogging persists, make sure the air
conditioning ( page 272) is activated, or
press button ;.
